Grapevine plant named ‘Sheegene 105’

ABSTRACT

‘Sheegene 105’ is a new and distinct grapevine plant with novel characteristics that include naturally loose bunches. The berries produced by ‘Sheegene 105’ are black and seedless with a very crisp texture and no detectable seed traces. The berries produced by ‘Sheegene 105’ are medium, weighing 6-7 g/berry on average, and are harvested in mid July in Spain (Murcia Region).

Latin name of the genus and species of the plant claimed: Vitis vinifera.

Cultivar denomination: ‘Sheegene 105’.

BACKGROUND OF THE INVENTION

The present invention relates to a new distinct variety of seedless grapevine named ‘Sheegene 105’. The variety originated from a hybridization performed in Mildura, Victoria, Australia during 2004 between ‘Stanley Seedless’ (unpatented), as the pollen parent, and ‘Autumn Royal’ (unpatented), as the seed parent. Abortive seed traces were embryo cultured and the resulting plant was planted in an evaluation block during 2006. The first evaluation of fruit produced by “Sheegene 105” was performed during 2009. ‘Sheegene 105’ was first asexually propagated by field grafting dormant hardwood scions to rootstock in 2010 in Irymple, Victoria, Australia. Fruit from the resulting sixteen grafted ‘Sheegene 105’ vines was first harvested in 2012. All characteristics and distinctions remain true to form and are established and transmitted through succeeding propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of ‘Sheegene 105’. ‘Sheegene 105’ produces medium and naturally loose bunches. The berries produced by ‘Sheegene 105’ are black (5RP 3/2) and exhibit a narrow ellipsoid shape, good evenness, and crunchy, neutral flavour.

‘Sheegene 105’ can be distinguished from its male parent, ‘Stanley Seedless’ based on upon berry color, shape and length. ‘Sheegene 105’ produces black-colored grapes; whereas, ‘Stanley Seedless’ produces green yellow berries. Additionally, ‘Sheegene 105’ berries exhibit a narrow ellipsoid shape; whereas, ‘Stanley Seedless’ berries exhibit a roundish shape. The length of ‘Sheegene 105’ berries (21 mm on average) is also shorter than that of ‘Stanley Seedless’ berries (23 mm on average).

‘Sheegene 105’ is believed to be most similar to ‘Autumn Royal’. Nonetheless, the new cultivar can be distinguished from its female parent, ‘Autumn Royal’, based at least upon vigor, berry shape and attachment, rudimentary seeds per berry, bunch size, and harvest period. ‘Sheegene 105’ displays a medium to high vigor; whereas, ‘Autumn Royal’ displays medium to low vigor. ‘Sheegene 105’ berries exhibit a narrow ellipsoid shape; whereas, ‘Autumn Royal’ berries exhibit an ovoid to ellipsoidal shape. The berries of ‘Sheegene 105’ are more strongly attached than those of ‘Autumn Royal’. The berries of ‘Autumn Royal’ also exhibit 2-4 detectable rudimentary (aborted) seeds that each weigh about 7.2 mg. In contrast, any rudimentary seeds within the berries of ‘Sheegene 105’ are undetectable. Additionally, the bunches produced by ‘Sheegene 105’ are smaller than those of ‘Autumn Royal’. ‘Sheegene 105’ is harvested in July in Murcia (Spain), which is earlier than the late August to early September harvest period of ‘Autumn Royal’ in Murcia (Spain).

‘Sheegene 105’ possesses some similarities with ‘Summer Royal’ (European PBR Certificate No. 30887). However, ‘Sheegene 105’ berries exhibit a narrow ellipsoid shape, whereas ‘Summer Royal’ berries exhibit a circular shape. The berries produced by ‘Sheegene 105’ are also heavier (6.6 g) than the berries produced by ‘Summer Royal’ (5 g).
